- Enable/Disable control
- Compact SMD package
Applications
- General clock generation
- Embedded systems timing
- Consumer electronics
Procurement Notes
Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct frequency and package specifications. Confirm that the 1.8V supply requirement aligns with your system design. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 4-SMD no-lead package fits your PCB footprint constraints.
Selection Notes
Select this component when a low-voltage 1.8V operation is required for clock signals. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. LVCMOS output is appropriate for standard digital interfaces. Consider the enable/disable feature if power management during idle states is necessary for the application.
Part Context
This model belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. The 'OE' suffix often denotes specific packaging or ordering options defined by the manufacturer. This series is part of Mercury's broader range of frequency control products including crystals and TCXOs.
Replacement Considerations
Direct substitutes may include other 8.0 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package with 1.8V operation. Verify pin compatibility and electrical parameters such as load capacitance and output swing before substitution. Consult Mercury Electronics for recommended alternatives if this specific part is unavailable.
